Title: Improvements relating to electric switch mechanisms suitable for controlling road traffic signals
IPC: G08G1/085
Filed: 1938-11-17
Abstract: 521,451. Snap-action switches; actuation of switches. GOWSHALL, Ltd., and MARKLEW, A. L. Nov. 17, 1938, No. 33415. [Class 38 (v)] In a switch specially suitable for controlling road traffic signals, a motor- or hand-driven spindle n is connected by a spring q to a switch spindle or sleeve j, the latter having projections p adapted to engage in turn one of two projections 12 on a gate 4 and hold the spindle j against movement until the spring q has been sufficiently strained when a projection 9 fixed on the spindle n engages a lever 10 and causes a movement of the gate 4 against the action of springs 8 thus releasing the projection p and allowing the spindle j to rotate until another projection p comes to rest against a second projection 12 on the gate. Further rotation of the spindle n causes the gate 4 to move back and release the projection p. The projections p when released pass through gaps 11 in the gate. The switch spindle j carries cams k operating switch arms. When the spindle n is hand operated a spring-pressed plunger engages a cam disc to determine the switch positions of the spindle n. The plunger may be withdrawn when the device is motor driven. The motor drives a ratchet wheel on the spindle n by reciprocating a pawl.

Abstract: 411,380. Enamelling iron. KREIDL, A., 6, Ettingshausengasse, Vienna. Nov. 29, 1933, No. 33464. Convention date, Dec. 7, 1932. [Class 56.] A process for enamelling articles of iron or steel without using a base enamel consists in subjecting the articles, before enamelling, to treatment by which there is formed, with the least possible simultaneous oxidisation of the iron surface, a coating of spinel-like nature. For this purpose, an article is brought to red heat in the presence of a coating containing metallic oxides and sesquioxides which are capable of combining to form spinels, and with the addition of fluxes, in an atmosphere of low oxygen content compared with air. The articles need not be etched and adherent rust may be left untouched. A suitable coating can be provided by a mixture of 100 parts of water, 5 parts of Fe2O3' 4 parts of NiO, 20 parts of CaF2, 45 parts of boric acid, and 10 parts of clay. An article is moistened with the mixture and after drying, is submitted to a temperature of 785-795‹ C. for seven minutes in an atmosphere in which, by admixture of producer or similar waste gases, the oxygen content has been lowered to between a fourth and a fifth of the usual value.

Title: Improvements relating to formes
Inventor: BISHOP THOMAS DESMOND
IPC: B26F1/44
Filed: 1963-08-28
Abstract: 1,007,549. Cutting-apparatus. DERITEND ENGINEERING CO. Ltd. Aug. 17, 1964 [Aug. 28, 1963; Sept. 5, 1963; Sept. 27, 1963]. Nos. 33971/63 Heading B4B. [Also in Division B6] A forme comprises a plate of soft material having at least one cutting or creasing rule impressed in a slot or groove which is created by pressing the rule into the material. The material may be a synthetic resin, e.g. polyethylene or polypropylene. In one form, Fig. 1, blanks are fed in direction of arrow A between a continuously rotating pair of rollers of which roller 20 carries a forme consisting of lengths of cutting or creasing rule. The impression roller is of rubber on a metal sleeve. In another form, Fig. 2, a platen 21 carries the forme and the material reciprocates first in direction B to take the material through the nip between the platen and impression roller 22 and then back in direction C for stripping the material from the platen. As shown in Fig. 5, the rule may be pressed through the thickness of the forme material and pads 40 of rubber or foam plastic are provided to act as strippers. The rule is provided with slots, Fig. 6, to allow the forme material to extend across and through the slots. In a modification. Figs. 8 to 10 (not shown), the rule is sinuous along the non- cutting or creasing edge and is only partly embedded in the forme material. In making the forme, rules 34, Fig. 11, are supported by blocks 35 above a sheet 36 of the forme material which is supported on a platen or roller 37. The cutting or creasing edges of the rules are covered by a metal sheet 38 backed by a platen or roller 39. If a flat forme, Fig. 2, is to be made all the parts 35 to 39 are flat so that a pressing operation pushes the rules into the forme. Where the die is for use as in Fig. 1, the nip between the rollers 39, 37 is closed to partly embed the rules and the rollers moved angularly to continue the embedding along the length of the rules.

Title: Block Synchronisation Circuit for a Data Communications System.

IPC: H04L1/00
Filed: 1967-07-26
Abstract: 1,195,065. Digital transmission systems. TELETYPE CORP. 26 July, 1967 [10 Aug., 1966], No. 34305/67. Heading H4P. In a data transmission system in which the data is transmitted in blocks, each block being accompanied by a block number and the blocks being transmitted without a break between them, the receiver has means for counting the blocks and for comparing the present count with that accompanying block just received, the receiver being inhibited for a preset period if the counts do not agree. To set up the system a calling signal is first transmitted to which the receiver responds by sending an " on " return signal when it is ready to receive. The transmitter then sends two block signals containing redundant data (these blocks ensure the correct phasing of the receiver counter) followed by a sequence of blocks. Each block comprises in sequence the block number (1, 2, or 3, cyclically), data, end of block, and error-checking redundancy signals. At the receiver, the received block number is compared with the number stored on a counter which is advanced at the end of each block. If the received number is low the receiver output is inhibited during reception of the block and the counter is not advanced at the end of this block. If it is high, the block associated with the number is cancelled from the receiver output, e.g. by overpunching, and the return signal is turned off. If the number is correct the receiver then determines that the end-of-block signal is present following a certain number of data signals: if it is not present the return signal is turned off. The block is also checked for errors using the received error-checking signals, and if an error is found the block is cancelled from the receiver output and the return channel turned off. At the transmitter, when the return channel turns off, the data input store is reversed for two blocks of data and the counter in the block number generator is reversed two counts. The transmitter then sets up the system again, starting with the calling signal as described above, and so the faulty block is repeated. To ensure that return line breaks do not cause faulty operation the errorchecking signal is added to the block only if the return signal is " on ": lack of this signal causes the receiver to initiate repetition as in response to a detected error.

Abstract: 344,459. Calculating - machines. MATHYS, A. W., 52, Chancery Lane, London.-(Monroe Calculating Machine Co. ; 555, Mitchell Street, Orange, New Jersey, U.S.A.) Dec. 5, 1929, No. 33869/30. Divided on 346,362. [Class 106 (i).] Differential mechanism.-In a machine having actuating-mechanism of the Thomas type each actuator device comprises two mutilated gear wheels mounted on a common shaft and adapted to come into action in succession to rotate corresponding pinions on the differential actuating shaft. As shown in Figs. 2 and 3 depression of a numeral key, through its broadened stem, displaces one or both of two differential bars 60, 62 each controlling, by a lateral arm 72, 82. the axial position of a pinion 86, 87 relatively to the mutilated gear wheels 89, 88. The gear wheel 89 has four stepped teeth and the pinion 86 is shifted one to four steps according as keys 1-4 and 6-9 are depressed. Gear wheel 88 has five teeth and its pinion 87 is placed in mesh with this wheel only when keys 5-9 are set. Thus according to the value of the key depressed one or both pinions will be driven so as to rotate the squared shaft 76 through the desired angle to drive the counter correspondingly. The gear wheels 88, 89 are disposed on their shaft 91 so as to come into action one after the other and all the shafts are driven by bevel wheels from a transverse shaft 94 rotated by a crank handle 44. Each shaft 76 is locked after gear wheel 88 has functioned, by means of the known Geneva stop and in order to prevent rotation of the shaft after the wheel 87 has passed, in cases wherein the drive by wheel 88 is not required, a further Geneva stop 109, 110 is provided, this stop being disabled, however, by the movement of the pinion 87 into effective position. The keys are latched down by pivoted bails 51 and the keyboard may be cleared by a universal bar 54 having lugs 55 to engage and rock the bails.

Title: Solid composition containing fat-soluble vitamins and processes for making it
IPC: A61K9/16
Filed: 1964-08-24
Abstract: Vitamin compositions in the form of a dry finely-divided free-flowing solid, insoluble in water at temperatures up to 100 DEG C., comprise a fat-soluble vitamin-active composition dispersed in a carrier of retrograded amylose.  The fat-soluble vitamins are A, D, E and K, and compounds having the activity of these, including precursors thereof. Particularly mentioned are vitamin A-alcohol, -aldehyde and its phenolic complexes such as retinol quinolate, -esters such as the acetate and palmitate, and the vitamin A precursor b -carotene; the E vitamins a -tocopherol and a -tocopheryl acetate, and the oil-soluble antioxidants butylated hydroxy anisole, butylated hydroxy toluene and ethoxyquin; and natural or synthetic products having vitamin D or K activity.  Retrograded amylose is described as a water-insoluble microcrystalline substance, formed by aggregation of colloidal amylose particles in aqueous solution on ageing the solution or by other treatments; it may be colloidally dissolved in water at superatmospheric pressure and temperatures of at least 150 DEG  to 160 DEG C.  The carrier may include edible plasticisers such as sugars, gums, methyl cellulose, or gelatin.  The compositions are prepared by: (1) Preparing an aqueous colloidal solution of amylose; (2) dispersing therein the vitamin-active composition; and (3) converting the dispersion, under conditions at which the amylose retrogrades, into dry solid particles.  The amylose solution is prepared suitably from pure retrograded amylose, by either solution in water at elevated temperature and pressure, or by agitation with aqueous alkali metal hydroxide; the vitamin active composition may be dispersed therein by simple stirring or agitation.  The third step may be effected by methods wherein the dispersion is agitated with, or extruded or sprayed into, a retrogradation medium, the latter being water or a non-polar hydrocarbon, e.g. hexane when the amylose has been dissolved in superheated water, or an aqueous solution of a neutralising agent, such as an ammonium salt of a strong acid, when the amylose is dissolved in alkali.  The retrograded particles are then removed from the medium, dehydrated (e.g. by air drying) and, if required, comminuted.  Alternatively, the dispersion may be simultaneously retrograded and dried, by spray drying, or drying on a heated continuous belt, or retrograded on a chilled belt and subsequently dehydrated, and then comminuted.  The product is useful as a vitamin concentrate for addition to animal or poultry feed.
